Abstract

A numerical algorithm is proposed to localize field singularities with the aid of the method of auxiliary sources using functions that describe converging and diverging waves. Effect of field singularities of particular pattern is studied in the problem of synthesis of an optimal antenna. It is shown that a desired pattern with minimum reactive field is obtained when the sources are located at such singularities. Results of numerical and real experiments are presented to prove the correctness of the proposed algorithm.
